Pioneer
The protagonist is a playable character that each player receives at the start of the game. After you kill a few mobs like Kafka, you will be able to choose between a male or female protagonist, which is how it usually works in Genshin Impact. This is technically a 5-star character, although it is free for all players, but it is not known if his power matches this title.
March 7

March 7 is a helpful 4-star support character that you get for free as you progress through the main story. She is the first free character you will get besides the main character. March 7 helps protect the squad with her shields, and is a great help for those who need a defensive advantage.
Dan Heng

Dan Heng is a 4-star character that you get for free during the main story. You'll get him as part of the initial tutorial quests around March 7. This character is mainly a single target DPS and a useful damage dealer when there aren't a lot of mobs around.
qingque

Qing Que is a 4-star character that requires players to complete several tasks before unlocking him. You will need to reach trailblazer level 21 and clear the Forgotten Hall - Memory Stage 3. The Forgotten Hall is similar to the Twisted Abyss in Genshin Impact and requires you to recruit two teams of four to take part in tough battles.
Asta

Asta is a 4-star character. You are guaranteed to get it during your Warp training. Using the free Star Rail Pass, all players are guaranteed to receive this character the first time they touch the Stellar Warp banner. Asta is a buffer that increases the attack and speed of his allies.
Serval

The Serval is a 4-star character that was given out for free to players as a pre-registration reward. If you haven't received it yet, please check your in-game mailbox. After that, you will also receive a free avatar, 20 Star Rail Pass tickets and 100 credits.
Natasha
Natasha is a 4-star character that you get for free by completing the quest Belobog-VI. She is a free healer who will help all the characters.
Hertha

Herta is a 4-star character that you can get for free after beating World 2 virtual universe.
Time-limited character events in Honkai Star Rail

Similar to Genshin Impact, HoYoverse allows players to earn free characters during limited-time events, so keep an eye out for any special gifts. The current Honkai Star Rail character giveaway rewards players with Serval, a deadly 4-star electric character.
The serval is given out to players due to Honkai Star Rail reaching 3 pre-registrations. The developers are likely to plan other limited-time events and character giveaways in the future.
